How often we feel and know, either pleasurably or painfully, that another is looking on us, before we have ascertained the fact with our own eyes! How often we prophesy truly to ourselves the approach of friend or enemy just before either has really appeared! How strangely and abruptly we become convinced, at a first introduction, that we shall secretly love this person and loathe that, before experience has guided us with a single fact in relation to their characters!
